The only thing I've found awful is the mindset of the people implementing the banners.
That you feel frustration over that every company has a cookie banner, is exactly the goal. The companies could decide that it isn't worth frustrating the user over something trivial like website analytics, as they could get that without having to show a cookie banner at all.
But no, they want all the data, even though they most likely don't use all of it, and therefore are forced to show the cookie banner.
Then you as a user see that banner, and instead of thinking "What a shitty company that don't even do the minimal work to not having to show me the cookie banner", you end up thinking "What a bad law forcing the company to inform me about what they do with my data". Sounds so backwards, but you're not the first with this sentiment, so the PR departments of the companies seems like they've succeed in re-pointing the blame...
